Claims raspberries boost fertility 'misleading'

Conclusion This cross-sectional research suggests that men with higher intakes of certain micronutrients have sperm with less DNA damage – in other words, their sperm is of a better quality. But there are limitations to this research. The main drawback  is that the research was a small cross-sectional study of 80 men. Cross-sectional studies cannot show cause and effect relationships – a randomised controlled trial would be required for this. As the researchers also point out, because of the correlation between the intake of different nutrients, it is difficult to determine whether the results seen are because of an overall high-quality diet, from one nutrient or certain nutrients in particular, or from one or several associated lifestyle factors. It is also important to note that regardless of any differences seen in sperm DNA, none of the 80 men studied actually had reported fertility problems. However, this research does not really provide the evidence to back up the news that raspberries boost fertility, which seems to be based on the opinion of one fertility nutritionist. Although a healthy balanced diet containing fresh fruit and vegetables has many health benefits and may improve sperm quality, this is not a basis for reports that raspberries boost fertility. Proven ways that men can boost their fertility include: quitting smoking (if they smoke) maintaining a healthy weight avoiding using illegal drugs such as cannabis mo...

This study aimed to explore the association of serum 25 ‐hydroxyvitamin D (25OHD) levels and semen parameters, as well as ART outcomes for men from infertile couples.Materials and MethodsThis study recruited 1,308 men from infertile couples who attended the Reproductive Medicine Center of Peking University Third Hospital for first time from February to August 2019(NCT03804294). Reproductive hormones levels, semen parameters and clinical outcomes of ART were compared between vitamin D deficient group (serum 25OHD ≤10 ng/mL), insufficient group (serum 25OHD 10‐20 ng/mL) and sufficient group (serum 25OHD≥20 ng/mL).R...

AbstractSelf-identified race/ethnicity and socioeconomic status (SES) contribute to disparities in several health domains, although research on their effects on women ’s reproductive function has largely focused on links between SES and age of menarche. Here, we assessed whether race/ethnicity, SES, and downstream correlates of SES such as food security and health-insurance security are associated with age of menarche, infertility, and live birth ratios (ratios of recognized pregnancies resulting in live births) in the USA. We used cross-sectional data from 1694 women aged 12–18 years for menarche (20...

In conclusion, although cigarette smoking does not seem to affect oocyte development, it had an effect on cytoplasmic anomalies and therefore may lower pregnancy chance. Therefore, it is crucial to give proper counselling to patients who are trying to become pregnant both naturally and by in vitro fertilization. PMID: 32338250 [PubMed - as supplied by publisher]

Abstract The dpy-19 like 2 (DPY19L2) gene is the most common genetic cause of globozoospermia characterised by the production of round-headed spermatozoa without an acrosome. The present study was performed on 63 men with globozoospermia and 41 normozoospermic individuals to evaluate the frequency of the DPY19L2 gene and exons; deletion and genetic changes in exons 1, 5, 7-11, 19, 21 and interval introns; and some epidemiological factors (e.g. varicocele, smoking, drug use, alcohol consumption and a family history of infertility). Homozygous deletion of DPY19L2 was identified in 35% of men with globozoospermia. Ex...

Abstract BACKGROUND: Parabens, which are used as a preservative in foods and personal care products, are detected in nearly 100% of human urine samples. Exposure to parabens is associated with DNA damage, male infertility, and endocrine disruption in adults, but the effects of prenatal exposure are unclear. In part, this is due to inadequate assessment of exposure in maternal urine, which may only reflect maternal rather than fetal exposure. To address this gap, we examined the association of prenatal methylparaben measured in meconium with preterm birth, gestational age, birthweight, maternal thyroid hormones, an...

In this study, we aimed to examine the effects of agar/polyvinyl alcohol nanofiber (PVA) scaffold on the proliferation efficiency and differentiation potential of neonate mouse spermatogonial stem cells (SCCs). Testicular cells were isolated from testes of 40 mouse pups and were seeded in: 1) 2D cell culture plates in the absence (2D/-GF) or presence (2D/+GF) of growth factors and 2) onto agar/PVA scaffold in the absence (3D/-GF) or presence (3D/+GF) of growth factors. The cells were subsequently cultured for 4 weeks. First 2 weeks were dedicated to proliferative phase, whereas the next 2 weeks emphasized the differen...

A 44-year-old man was evaluated for recurrent angioedema manifested as more than 10 discrete episodes with swelling of the posterior pharynx and uvula, without urticaria, that would subside spontaneously over 24 hours. These episodes were first noted 2 years ago, were worsened by alcohol, and were not responsive to antihistamines. Medical history was significant for hyperestrogenism, that worsened with testosterone treatment for infertility. His primary family history revealed a father and brother with gynecomastia, a mother with endometrial cancer, and a sister with Lynch syndrome.

In this study, we examined whether smoking and drinking affect sperm quality and the DNA methylation of the repetitive element LINE-1, MEST, P16, H19, and GNAS in sperm. Semen samples were obtained from 143 male residents in a minority-inhabited district of Guizhou province in southwest China. Quantitative DNA methylation analysis of the samples was performed using MassARRAY EpiTYPER assays. Sperm motility was significantly lower in both the nicotine-exposed (P = 0.0064) and the nicotine- and alcohol-exposed (P = 0.0008) groups. Follicle-stimulating hormone (FSH) levels were higher in the nicotine-exposed group (P = 0.0026...

CONCLUSIONS: This retrospective cohort study demonstrated that patients who underwent ART were at increased risk of several adverse pregnancy outcomes compared with women who conceived spontaneously. These complications may be attributed in part to the relatively high multiple pregnancy rate after ART. Elective single embryo transfer should be promoted in China to reduce the obstetrical risks of ART pregnancy. Singletons of ART pregnancy exhibited increased maternal and neonatal complications as well, suggesting that underlying infertility or other maternal or parental factors may contribute to the adverse outcomes. P...
